Backflow Prevention Practice Exam

A swing connection is a type of _____?

1. Backflow preventer

2. Cross-connection

3. Detector assembly

4. Gauge component

The correct answer is: Cross-connection

A swing connection is classified as a cross-connection because it serves as a point where potable water could potentially come into contact with non-potable water under certain circumstances. In plumbing systems, a cross-connection refers to any actual or potential connection between a drinking water supply and any source of contamination. Swing connections are often used in irrigation systems, fire protection systems, or similar applications where there's a possibility of backflow from non-potable sources. Understanding swing connections as cross-connections is crucial for backflow prevention efforts, as they highlight the importance of implementing proper backflow prevention devices to mitigate the risks. This classification helps professionals identify potential hazards in water supply systems, facilitating better system design and compliance with health standards.
